Texas Instruments UCC21521
The UCC21521 is an isolated dual-channel gate driver with 4-A source and 6-A sink peak current. It is designed to drive power MOSFETs, IGBTs, and SiC MOSFETs up to 5-MHz with best-in-class propagation delay and pulse-width distortion. The input side is isolated from the two output drivers by a 5.7-kVRMS reinforced isolation barrier, with a minimum of 100-V/ns common-mode transient immunity (CMTI).| Part No. | UCC21521 |
